Abstract
The invention relates to a high oxygen permeation type orthokeratology lens for molding cornea in a sleep state. The contact lens has the high oxygen permeation rate, can perfectly maintain the original molding effect of a molding lens and is relatively safe. The technical solution is as follows: the high oxygen permeation type orthokeratology lens for molding the cornea in the sleep state comprises a spherical fluorosilicone acrylate lens main body; the high oxygen permeation type orthokeratology lens is characterized in that a plurality of vent holes are formed in the whole lens main body to form a netty structure, and the vent holes respectively penetrate through the lens main body in the thickness direction.
Description
Technical field
The present invention relates to a kind of contact lens, be specifically a kind ofly specifically designed to corneal under sleep state and carry out moulding cancellated high oxygen flow Ortho-K.
Background technology
At present, all contact lenss, comprise that Ortho-K all needs to solve a key issue, are exactly oxygen flow problem.Can say that oxygen flow is one of this series products success or failure key factor of contact lens.
Therefore when research and development contact lens, people always break through on the starting material of contact lens, select or invent the various lens materials with high oxygen transmission rate; Fluorine silica acrylic acid fat is exactly a kind of like this lens materials with high oxygen transmission rate, though fluorine add the oxygen transmission rate that can improve material, can reduce the physical strength of material simultaneously, eyeglass is easily scratched, cracky.
Summary of the invention
The object of the invention is to overcome the deficiency in above-mentioned background technology, providing a kind of is specifically designed to corneal under sleep state and carries out moulding cancellated high oxygen flow Ortho-K, this contact lense have oxygen transmission rate high, simultaneously still can retain in good condition the feature of the moulding effect of former moulding mirror, and safer.
Technical scheme provided by the invention is: a kind ofly for corneal under sleep state, carry out moulding high oxygen flow Ortho-K, comprise the fluorine silica acrylic acid fat eyeglass body of spheric; It is characterized in that forming reticulate texture after described eyeglass body entire body is arranged a plurality of bleeder vents, these bleeder vents run through eyeglass body at thickness direction respectively.
The bleeder vent aperture distributing in the orthopedic district of central authorities of described eyeglass body central area is 0.3-0.35mm, and the bleeder vent aperture in circumferential annular region, central orthopedic district is 0.5-0.8mm.
Hole dutycycle in the orthopedic district of described eyeglass body center is 72-73%.
Principle of the present invention is: the ratio by reasonable control hole area with eyeglass entire area, the most areas that make cornea by hole all can with tear even air directly contact, so just can thoroughly solve the problem of wearing the oxygen supply of moulding pitch-angle film night.
The invention has the beneficial effects as follows:
The present invention does punching at eyeglass body (the orthopedic district of central authorities that comprises eyeglass central authorities) and processes; And the dutycycle of controlling hole is 72-73%, and most corneas all can directly be contacted with tear, solved well the moulding contradiction with cornea oxygen supply at night.Secondly, practice shows, the dutycycle of central orthopedic district 72-73% does not affect and gets up in the night to urinate and indoor walking, uses fool proof.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Fig. 3 is plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the present invention is not limited to following examples.
The corneal under sleep state that is specifically designed to is as shown in Figure 1 carried out moulding cancellated Ortho-K, comprises the eyeglass body 1 of spheric; The central area 1-1 of described eyeglass body is central orthopedic district (being base arc region, for correcting defects of vision), and the annular region 1-2 that is centered around central orthopedic district surrounding is the orthopedic districts of non-central authorities.
State in the orthopedic district in the orthopedic district of central authorities and non-central authorities of eyeglass body and be all shaped with some bleeder vents 2, these bleeder vents run through eyeglass body (running through spherical inside surface and the spherical outer surface of eyeglass body) at thickness direction, and the dutycycle of the bleeder vent ratio of the total area (hole area with) is 72.54%.
The distribution in aperture: what cornea periphery was mainly had in mind is the problem of oxygen supply area, so periphery generally distributes to such an extent that be mostly that large aperture hole, diameter are 0.5-0.8mm.
And what stress within the scope of central orthopedic district ￠ 6mm is moulding effect, take into account oxygen transmission rate simultaneously.Bleeder vent in this region is that diameter is the small-bore of 0.3-0.35mm, and it is uniform to be high density.Because aperture is little, and between cornea and eyeglass body, have one deck tear film, add anterior corneal surface tension force, anterior corneal surface can not be protruding in hole, thereby also will not as in the imagination, leave spot printing and affect moulding effect at cornea table.Meanwhile, air can contact with the tear in cavity volume by these bleeder vents, improves the oxygen-supplying amount of cornea, and then reduces the generation of disease of cornea.
These bleeder vents generally make (being prior art) by laser boring method.
It is worthy of note: according to traditional theory, the central optical zone of eyeglass is used for realizing dioptric function, a hole does not allow to exist yet.Core value of the present invention is exactly the micropore that gathers in the central optical zone of moulding mirror, thereby realizes moulding and two functions of oxygen flow simultaneously.
